A cyclist was killed today in a collision with a garbage truck in North Portland, the city's second fatal collision this month involving a bicycle and a heavy truck. The crash occurred at about 12:30 pm., as the garbage truck, a white SUV and the cyclist were all headed south down North Interstate Avenue. Police said both motor vehicles had passed the cyclist at the top of the hill. As the garbage truck approached the green light at North Greeley Avenue, it slowed down and started to take a sharp right turn. The cyclist, who had gained speed from the descent, was headed straight when the truck turned. The cyclist was crushed by the truck's rear set of tires.
